2nd Edition/Revision 3 (3/4/04)

HINT: Because the flow

switch only closes when

water is flowing, the heater

resistance can only be

measured at the heater

terminals (not at the control

module).

HINT: The NTC and

High Limit are contained

in the same part. When

either fails, replace

entire part # 165281.

Use dishwasher test

program to turn on

heater, then measure

dishwasher incoming

current. If ~ 1.5A,

heater, Hi-Limit, flow

switch or circulation

pump has failed.

Check voltage @

module (or timer) -- if

0V, module (or timer)

has failed.

For electronic models,

current can also be

measured through

red heater

wire at

control module (~

9.5A). Since there

can be more than one

red wire, check wiring

diagram to select

heater wire.

NOTE: Open door to run test

program for fully-integrated models.

NOTE: Flow through heaters heat

water ~ 2ºF / minute.
